This line of code is casting the pointer 'temp' to an integer pointer and then dereferencing it to get the value of the integer it points to.
Explanation:
- 'temp' is a pointer to some memory location (we don't know what type of data it points to).
- `(int*)temp` is casting this pointer to an integer pointer, indicating that we want to treat the memory location as an integer value.
- `*((int*)temp)` is dereferencing this integer pointer to get the value of the integer it points to.
- This value is then assigned to the integer variable 'num' using the assignment operator '='.
Overall, this line of code is useful when we have a pointer to some memory location but we know that the data at that location is of integer type, and we want to retrieve that integer value.
